Frequently Asked Questions (FAQs)
Q1: Can I complete the entire Aadhaar application process without visiting an enrollment center?
A: No, as of 2026, a physical visit to an enrollment center is still mandatory for first-time applicants to provide biometric data (fingerprints, iris scan, and photograph). However, most of the documentation and appointment scheduling can be completed online. For updates to existing Aadhaar (except biometric updates), many changes can be completed entirely online through the UIDAI Self-Service Update Portal.
Q2: What should I do if my mobile number is already linked to another family member’s Aadhaar?
A: Each Aadhaar should ideally have a unique mobile number for security and OTP purposes. If your number is linked to another person’s Aadhaar, you have two options: (1) Use a different mobile number for your application, or (2) Update the existing Aadhaar to remove your number before using it for your application. Family members can share a number in exceptional circumstances, but this limits certain digital services.
Q3: How long is the Aadhaar card valid? Does it need renewal?
A: Aadhaar is valid for a lifetime once issued. However, UIDAI recommends updating your photograph every 10 years after age 15 to maintain current appearance records. For children, biometric updates are mandatory at ages 5 and 15. Demographic information (address, etc.) should be updated whenever changes occur.
Q4: Can I apply for Aadhaar if I don’t have any of the standard proof of address documents?
A: Yes, UIDAI offers alternative procedures. You can submit a certificate of address issued by a Gazetted Officer, Tehsildar, MP, MLA, or Village Panchayat head. Alternatively, you can use the “Introducer” system available at enrollment centers, where a pre-verified Aadhaar holder can vouch for your identity and address.
